A funeral is a ceremony for celebrating, sanctifying, or remembering the life of a deceased person. Funerary customs comprise the complex of beliefs and practices used by a culture to remember the dead, from the funeral itself, to various monuments, prayers, and rituals undertaken in their honor. These customs vary widely between cultures, and between religious affiliations within cultures. In some cultures the dead are venerated; this is commonly called ancestor worship. The word funeral comes from the Latin funus, which had a variety of meanings, including the corpse and the funerary rites themselves. Funerary art is art produced in connection with burials, including many kinds of tombs, and objects specially made for burial with a corpse.

Funeral rites are as old as the human culture itself, predating modern homo sapiens, to at least 300,000 years ago. For example, in the Shanidar cave in Iraq, in Pontnewydd Cave in Wales and other sites across Europe and the Near East, Neanderthal skeletons have been discovered with a characteristic layer of pollen, which suggests that Neanderthals buried the dead with gifts of flowers. This has been interpreted as suggesting that Neanderthals believed in an afterlife.
